The heating element(2) is connected on an electricity source(3) of over 80V. The heating element(2) is made of refractory metals with a sectional area of over 5 square millimeters. An insulating layer(6) is arranged on the heating mould(1). The utility model can increase the diameter of the heating element(2) and the heating area, and decrease the heating time. Heating is evenly provided so the anti-ablation and antioxidation abilities are greatly improved. The service life is so long that the heating device will need no maintenance within ten years. The device has so good insulation effect that the heating temperature can be controlled below 500 Celsius system to provide good energy saving effect.
Description
Technical field the utility model relates to firing equipment, particularly is used for the heater on the rubber processing machinery.
The conventional heating technique of background technology is to adopt the heating of power-frequency voltage total head, because heating voltage and temperature are higher, to having relatively high expectations of insulating barrier, generally use high-quality mica sheet or pottery, quartz sand as the partiting thermal insulation material, higher and the complex process of cost, and because what carry out is full voltage heating, heating-up temperature is more than 800 ℃, the insulating materials of electrothermal device more easily produces electrical breakdown, thermal ablation phenomenon, greatly reduces the reliability of electric heater unit.In addition, the heating wire diameter of routine techniques is less, heating-up temperature is higher, add the reason of conventional total head heating wire owing to manufacturing process and metallurgical technology, diameter is little having, length is big, it is inhomogeneous easily to produce the heat radiation that causes on the inhomogeneous and manufacture craft of resistance, the localized heat that very easily produces heating wire is ablated, factors such as high-temperature oxydation, very easily cause the damage of heating element heater, make heating element heater unreliable because of quality, produce the short and disadvantage that can't effectively be incubated in service life, owing to can't firing equipment effectively be incubated, what cause that conventional heater takes on process structure is that standard-sized sheet is put the external-heat structure, its heating element heater is exposed in the air fully, cause the efficiency of heating surface low, the production environment inclement condition, and the temperature in when heating is subject to external interference and produces drift.Also have a considerable amount of equipment to use steam heated, its thermal conversion efficiency and heating-up temperature are low all lower, also have problems such as water and vapour leakage, have a strong impact on the improvement of product precision and production environment.
Summary of the invention the utility model adopts the low pressure heating technique, solves heating element heater insulating requirements height in the prior art, the technical problem of cost increase and easy electrical breakdown.The utility model adopts heating element heater to add the insulation measure outward, and the thermal efficiency is low in the solution prior art, wastes serious technical problem.
The utility model is realized by implementing following technical scheme: a kind of rubber processing machinery heater comprises the compression molding heated die plate, the heating element heater that is provided with on heated die plate; Described being connected on the following power frequency supply of 80V, described heating element heater adopts sectional area to surpass 5mm
2Metal make.Owing to adopt the low-voltage power supply scheme, the corresponding increase of diameter that can make heating is more than tens times, heating current increases more than tens times, makes effective area and the diameter increase and the length minimizing of heating, adds the low-temperature heat technology of taking, heating surface (area) (HS is increased, heat more evenly, it is anti-ablates, antioxygenic property greatly strengthens, and prolonged its service life greatly, under the condition of making material and technological requirement strictness, its heating element heater can accomplish substantially 10 years non-maintaining.
This device has adopted the technology of low-voltage power supply, so, efficiency of heating surface height, good heat insulating, have safe and reliable, cost is low, the characteristics of good energy-conserving effect.
